Bathymetry Meaning in Surfing

Bathymetry is the study of the underwater depth and shape of the seafloor. The topography of the ocean bottom determines how and where waves will break. Swells change shape as they move from deep water to shallow reef areas. Precise bathymetry data helps scientists and surfers predict the quality of a break. A reef with a steep drop creates a much more hollow wave. A surfer studies the bathymetry of a local beach to find sandbars today. The underwater landscape is the primary architect of every single surfing wave on earth. One scientist maps the deep canyons that focus energy toward the famous beach. Knowing the seafloor helps a surfer understand the secrets of their favorite spot.
